Geometry

Can you please help me set up these two problems. I am having a difficult time getting started and knowing where to take the problem. Thanks

The "pitch" of a roof refers to the vertical rise measured against a standard horizontal distance of 12 inches. If the pitch of a roof is 5 in 12 (the roof rises 5 inches for every 12 horizontal inches), find the acute angle the roof makes with a horizontal line. Round your answer to one decimal place.

Select the correct answer.

a. 65.4 o

b. 67.4 o

c. 24.6 o

d. 22.6 o

The distance between two buildings is 160 feet. You are standing on the roof of the taller building. You measure the angle of depression of the top and bottom of the shorter building. If the angles are 36.2 o and 71 o, respectively, find the height of the shorter building. Round to the nearest foot.
